Application filed. November 10, 1919.

To all whom t may concern.'

Be it known that l EDWARD J. VOGEL, a citizen of the United States, residing at San Francisco,.in the county of San Francisco and State of California, have invented new and useful Improvements in Golf-Ball Practice Substitute, of which the following is a specification.

The object of the present invention is to provide a substitute for a golf ball for practising driving or hitting the golf ball, which, after being hit or driven by the golf club, will immediately return to its original position in readiness for another stroke of the golf club, and will require no teein up.

In the accompanying drawing, igure 1 is a vertical longitudinal sectionof my improved golf ball substitute, showing also in vertical section a mat used in connection therewith; Fig. 2 is a vertical section of the mat as it appears before the substitute golf ball is attached thereto; Fig. 3 is a plan View of the substitute golf ball; Fig. e is a horizontal sectional View on the line 1 -4 of Fig. l; Fig. 5 is a front view thereof; Fig. 6 is a sectional view on the line 6--6 of Fig. l; Fig. 7 is a perspective view of the mat and substitute golf ball.

Referring to the drawing, 1 indicates a mat, preferably of rubber and preferably of one half of an inch in thickness. Through said mat iscut a recess hole 2 and through said hole 2 is passed a rubber tongue 3 secured at the lower side of said mat by a broad headed screw 4 countersunk in the upper part of the mat and a nut 6 screwed on said screw 'and countersunk in said tongue. rlhe tongue 3 extends through the hole 2 above the mat, and, above the mat it is externally, and viewed from above, of a somewhat globular form, as shown at 7, and of the same; dimensions as an average sized golf ball, being curled over, as shown at 8, and extending downward, as shown at 9, so that the globular portion 7 appears to be raised above the surface oi the mat to the same height as a golf ball when teed up. The sides ci the globular portion 7 of the strip taper gradually in thickness to the edge, as shown at 10 in Fig. 6.

lt results from this construction that the substitute golf ball, when viewed from the' position ci a player addressing the ball, presents an appearance sufficiently like to a gol't ball to be a perfect substitute therefor in practising. The giohular portion ot the Specification of Letters Patent.

strip may be formed with a brambled or dimpled surface, as desired, and will be colored white in contrast to the mat, which is colored green, to further simulate a golf ball teed up.

I preferably, although not necessarily, provide the globular portion 7 of the ball with a small protuberance ll at the point where the club strikes the ball substitute, for two reasons :-first, to assist the player in keeping his eyes on the exact spot to be struck by the club, and, second, to strengthen tllie ball substitute against the impact of the c ub.

W'hen the substitute ball is struck by the club, it will yield to the blow of the club, assuming the position shown in dotted lines in Fig. l, so that the club head will pass over the strip in the natural course of its swing, the comparatively thin edges 10 ofthe strip straightening out to permit the club head to pass thereover. Immediately that the club head has passed over the substitute ball, andlong before the player is ready for another stroke, the substitute ball will spring back to its original position.

The resistance offered by the ball substitute to the impact of the club is not more than the resistance oiiered by an ordinary ball to said impact.

I have found a satisfactory composition for the golf ball substitute to be 40% para rubber and the remainder of :first class mineral matter, not including more than 3% sulfur, which percentage includes the sul-fur in the mineral matter.

l claimzl. A goli ball practice substitute formed of a strip of elastic material, one terminal portion of which is adapted to be attached to the/under side of a mat or the like, the

mat or the like being termed with a hole through which the portion of the substitute adgacent to said terminal portion can entend,

eef

the other terminal portion of the strip being free, and the portion of the substitute adjacent to the latter terminal portion being formed to resenble, when viewed from above a golf ball.

2. A golf ball practice substitute having an upper portion somewhat resembling a golf ball, a lower portion provided with means for retaining it in position, and an intermediate self-sustainingneck-like portion formed of elastic material and connected with one side only of the upper portion.

3. A golf ball practice substitute of elastic material having a self-sustaining upwardly extending portion somewhat resembling`7 when viewed from above, a golf ball, a lower portion provided with means for attachment to a mat7 and a neck-like )portion of the same material connected with one side only of the upper portion.

4. A golf ball practice substitute comprising a strip of elastic material adapted to be attached to a mat or the like, the upper pori tion of the strip being formed topresent the appearance, when viewed from above; of a golf ball and being curled over inthe direction of the strip, and being attached to the strip at the side only from which it is curled over. l
